Neverwinter Nights: Hordes of the Underdark

The world is ignorant. Most will sleep away the blackest night and awake to welcome the new light of dawn secure that the light always returns. Not for all. Deep under the crust of humanity and civility is a place where nightmares never rest. Where the light of day cannot shine and slithering horrors dwell in the pits only seen in the visions of a madman. An entire world waits to be explored. An entire world waits for a bringer of light. The Underdark waits.
